Most helpful review for Minelab GPX-4500

GPX-4500 review
One of the best performing detectors for finding gold. I have used every
model of minelab detectors and find that this is one of the best. It has
more features than the previous models including digital control. If you
get confused with the setting up it can be set back to factory settings by
holding the power switch on for 5 seconds. I upgrade these detectors for
prospectors around the world.Detectormods from Melbourne Australia
